Guys are weird

So I have this guy that I like I guess you can say we are fwb  he told me he didn't want to be in serious relationship and I'm cool with that . I'm a virgin and when I finally told him he was shocked but he was fine with it . But he's so confusing sometimes like I give him chances to sleep with me yet he never takes it yet when we text he always talks dirty with what he wants to do with me  . But when I tell him he confuses me how one minute he wants to sleep with me then the next he doesn't . Then he goes on about how he doesn't want to just sleep with me he wants to see me . Which I mean I want to see him to I know it's not all about sex but sometimes it's like he want a relationship yet he doesn't .most guys would just want to sleep with you that's it . Sorry about going on like this I just needed to get this off my mind 😐
